This is a user problem reading + understanding manual:
The figure says 224 is free ( = 128(EPDC) + 64(128 - 64res) + 32(PXP) ), and "see note".
In note: "The entire OCRAM region can be used freely post boot. ... "
So can the entire OCRAM 288KB be used freely post boot, or only 224? (I can't say why I can't understand the doc ... ).
And if the 64KB is still reserved, what is it reserved for .. (is it secret ) ?
